Grout(LS)

DESCRIPTION: AT-GROUT (LS) is a ready-to-use cement grout that expands in two stages to sufficiently counter the plastic shrinkage normally associated with cement grout. It is a blend of Portland cement, chemical additives and graded fillers. Only water needs to be added.
STANDARDS: AT-GROUT (LS) complies with ASTM C827 & C1107
USES:

  • Machine base plates
  • Anchor bolts
  • Cavities gaps and recesses
  • Bridge bearing packs
  • Anchoring a wide range of fixings
  • For precisions grouting where it is essential to withstand static and dynamic loads

ADVANTAGES:

  • Easy to mix and apply
  • Rapid strength development
  • High final strength
  • No metallic iron content, hence no chance of staining
  • No segregation or bleeding
  • Gaseous expansion system compensates for shrinkage
  • Non-toxic and safe to handle

COVERAGE:

  • 2.0 kg (approx) will yield 1 ltr. fluid grout

INSTRUCTIONS FOR USE: Surface preparation: All surface laitance and unsound concrete must be chipped away so that a reasonable rough, but strong and sound surface is provided. Surface must be free from oil, grease and dust; this particularly applies to the underside of bed plates, bolts, pipes or other materials which may have surface contact with the grout. After cleaning, there should be no standing water present on surface of foundations or in bolt holes before application of AT-GROUT (LS). MIXING: AT-GROUT (LS), is best mixed with mechanical mixer. Powder is gradually added to pre-measured water and mixed mechanically with slow speed drill until a smooth and even consistency achieved.

APPLICATION: Pour the fluid grout after mixing from one end only. Ensure air to escape. For flowing grout sufficient head pressure have to be ensured.

CURING: After the grout is initially hardened curing has to be done with damp Hessian. TECHNICAL DATA:
